Bidirectional Cable Management Arm Connection Device
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing connection devices for cable management arms and slide assemblies restrict the width and space when installed, as plungers protrude beyond the chassis, making it difficult to remove the cable support arm from the rails, especially when the chassis needs to be removed from a storage position, as the release mechanism is complicated and limited to one direction.
Innovation Solution
A connection device with a connection member featuring bent portions, a sidewall with a T-shaped window, and an engaging member with a resilient arm and insertion piece, allowing the insertion arms to be inserted from both sides, enabling the connection to be released from two opposite directions, reducing protrusion and enhancing space efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If plungers are used to connect the cable support arm to the rails, then the connection can be made securely, but the plungers protrude beyond the chassis and restrict the width and space when the chassis is installed in the rack
Solution Approach 1:
The plunger is nested within a recessed cavity in the connection member, allowing the plunger to be housed inside the chassis structure rather than protruding outward. This nesting arrangement maintains the connection function while eliminating the space restriction problem caused by protruding plungers.
2Ease of manufacture
If plungers are used for connection, then the connection can be made, but when the cable support arm is removed from the rails, the plungers provide only one removal direction, making it difficult to release the connection when the chassis needs to be removed from storage position
Solution Approach 1:
The connection member is segmented into multiple functional components: a recessed cavity housing the plunger, a window providing access to the plunger from opposite sides, and a resilient button mechanism. This segmentation allows the plunger to be actuated from either side of the chassis, enabling removal in multiple directions and greatly facilitating the release of the cable support arm from storage positions.
Solution Approach 2:
Instead of providing a single-direction plunger push mechanism, the design inverts the approach by creating a window that allows plunger actuation from both sides of the chassis. This inversion of the single-direction constraint enables bidirectional operation, making it easy to release the connection regardless of which side the chassis is accessed from.
3Ease of operation
If the connection device allows release from two sides, then the removal complexity is reduced, but the structure becomes more complex with additional components like window and resilient arm
Solution Approach 1:
The resilient button mechanism serves multiple functions simultaneously: it acts as the actuation mechanism for the plunger, provides the release button for user operation, and serves as part of the window structure. By merging these functions into a single integrated component, the design achieves bidirectional release capability without proportionally increasing structural complexity.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The connection device allows for easy and convenient release of the cable management arm from the slide assembly in both directions, reducing the complexity of removal and minimizing space occupation, while maintaining secure positioning.
Implementation Method 1
An engaging member is fixed to the sidewall of the connection member and has a resilient arm and an engaging portion, wherein the resilient arm extends to the window of the connection member

AI summary
A connection device (14) for a cable management arm (10) and a slide assembly (12) includes a connection member (26), an engaging member (28) and an insertion piece (30). The connection member (26) is fixedly connected to the cable management arm (10) and includes a passage (36) and a window (38). The engaging member (28) is fixedly connected to the connection member (26) and has a resilient arm (46) and an engaging portion (48). The resilient arm (46) is located corresponding to the window (38). The insertion piece (30) is fixedly connected to the slide assembly (12) and has two insertion arms (52). One of the insertion arms (52) has a contact section (56) located corresponding to the engaging portion (48). When the insertion piece (30) is inserted into the passage (36), the engaging portion (48) of the engaging member (28) contacts the contact section (56) of the insertion arm (52) to position the insertion piece (30) to the connection member (26).
